Get in the mood with the Austin 7 Club, military vehicles, and learn of life in wartime Britain, including home front cooking and ration books. There’ll be fun for all the family, with code-breaking, face-painting, kid’s trails and puzzles, a prize for the best dressed 1940s-styled visitor, and even a specially brewed Auxilier Ale. The National Trust's weekend-long event marks the 70th anniversary of the British Resistance Organisation or Auxiliary Unit, which had it's hush-hush headquarters at Coleshill - and where over 3,000 men were secretly trained during WWII. A new bunker has been built underground and will be officially opened over the weekend. Built thanks to Heritage Lottery Funding, this new underground base is an exact replica of the original 70-year-old training “funk hole” at Coleshill. Alongside the recently refurbished Guards House, it is hoped that the bunker will offer a vital insight into the world of the brave Auxiliers, the country’s last line of defence in case of invasion by Hitler’s Germany. Find out more about Coleshill's fascinating history at our series of talks over the weekend. 11am to 5pm (4pm Sunday) Admission £3 adult, £1.50 child.
